I do have a suggestion for you as your mails are important to you.
You can make a quick backup of your Message Store, if you have enough free Hard drive space.
Use the shortcut to open the Message Store folder.
Click the Up icon to move up one directory so you have the Outlook Express folder showing (this is the same thing you did to create the shortcut).
Copy the Outlook Express folder either to your My Documents folder or to the Desktop. Be sure to only copy, not move.
You can move the copy to an external drive or burn it to CD for safe keeping (in case your Hard drive ever fails, you'll still have your old mail).
If you want to burn it to CD, it's over 3GB so you'll need to open the folder and burn the individual DBX files to a few CD's. If you ever need to restore from them, they will need to all be placed back into a folder together on your hard drive, so be sure to keep the CD's together.
One final note:
Don't store messages in the default folders in OE (Inbox, Sent Items, Deleted Items, and Drafts). Delete what you don't want to keep and move everything else to folders of your own creation. Try to keep the size of the folders to 100MB or less.
Each folder you create in OE will have it's own DBX file created in the Message Store folder. More, smaller files are better. If one should corrupt or otherwise fail, you won't risk losing as much.
I highly recommend doing that before you Compact messages again. The larger the DBX file size, the more likely that Compacting can corrupt them. And yes, Compacting is necessary for the proper operation and maintenance of OE.

Be sure to hang onto that shortcut. It's very handy to have.
